 Shear strengthening of RC beam using RFRP composites Partial or complete replacement of non-renewable composite materials with natural fiber reinforced polymer composites, such as basalt fiber, carbon fiber and glass fiber reinforced polymer composite can reduce the consumption of non-renewable resources and damage to the ecological environment in civil engineering construction. It is of great significance for solving global warming, developing green manufacturing and low-carbon cities, and promoting sustainable development in civil engineering. Therefore, this paper focused on mechanical properties of ramie fiber reinforced polymer (RFRP) composites. Futhermore, the shear capacity of RC beams strengthened with ramie fiber sheet was studied, and the bearing characteristics and failure modes of RC beams strengthened with fiber reinforced polymer composites was analyzed. The results show that after the surface treatment with dilute hydrochloric acid, silane coupling agent (KH-550 and KH-560) and aluminum zirconium coupling agent, the mechanical properties of RFRP composites enhanced significantly. Moreover, the surface wettability and interfacial properties of ramie fiber to the epoxy resins were improved by about 40 %. The shear strength results show that after the reinforcement of ramie fiber sheets, the bearing capacity and mid-span deflection of RC beams were greatly improved, and the silane coupling agent (KH-560) modifying ramie fiber sheets had better reinforcement than other fiber sheets. It could be concluded that the replacement of ordinary fiber sheets by ramie fiber sheets can not only reduce the consumption of non-renewable resources, but also improve the shear resistance of RC beams strengthened with the fiber sheets. 10.34910/MCE.114.1 69.07 natural fibers surface treatment strength of materials shear stress https://engstroy.spbstu.ru/article/2022.114.1/

 Fracture characteristics of high-performance concrete using nano-silica High-performance concrete (HPC) using nano-silica (NS) has higher mechanical properties and durability than conventional concrete. The highly active silica ultrafine particles have improved the performance of HPC significantly. The fracture characteristics of HPC are also enhanced when using NS due to the improved quality of C-S-H gels and the interface transition zone between mortar and aggregate. The influence of NS on fracture characteristics of HPC is considered in the study as a basis for the effective application of HPC in the structure of buildings. The paper assesses the influence of NS on the strength and fracture characteristics of HPC. HPC mixes were produced by replacing Portland cement with NS at 0.5 % and 1.5 %. The fracture testing for HPC using NS was carried out based on the three-point bending test of beams with the notch. The result is the load-crack mouth opening displacement relationship curves (P-CMOD) and load-deflection (P-). Finally, fracture parameters and characteristics of HPC using NS are analyzed and calculated from the P-CMOD and P- relationship curves. 10.34910/MCE.114.2 691.54 high-performance concrete nano-silica fracture characteristic fracture parameter https://engstroy.spbstu.ru/article/2022.114.2/

 Model of soil thermal conductivity in the form of a truncated sphere The model is designed for a three-phase soil system: mineral part, water, and air. The model's input parameters are porosity and water saturation coefficient, which characterize the volumetric ratio of the main components in the soil. The soil thermal conductivity model is represented as a sphere of the mineral part in the sphere of water. A cube - a unit volume, truncates both spheres. The main design parameters are the radii of the spheres of water and air. A single volume was divided into several heat flow paths with the same set of soil components, for each of which the thermal conductivity was calculated as for a multilayer wall. The total thermal conductivity was calculated by averaging, taking into account the cross-sectional areas of each of the paths. Depending on the values of the design parameters and their relationship, the model has identified three design cases. An analytical solution is obtained for each design case. Comparison of the calculation results using the developed model showed good agreement with experimental data and existing thermal conductivity models. 10.34910/MCE.114.3 624.131.436 theoretical analysis theoretical prediction model thermal conductivity porosity soil thermal conductivity model https://engstroy.spbstu.ru/article/2022.114.3/

 The method of determining the trend equation for predicting vertical displacements by the search method of nonlinear programming Observing the settlement of buildings and structures often gives rise to the question of their prediction. This primarily requires determining the form of the time series trend equation, which would describe by a single law all sequences of the time series compiled from geodetic data. The procedure for determining the trend equation of the time series is carried out by linear and nonlinear regression analysis. However, these methods have a number of drawbacks. In this connection, the case study of changing the benchmarks values of one of the deformation marks is considered in order to analyze the possibility to apply the search method of nonlinear programming for determining the trend equation on the basis of the geodetic measurements data. A method of constructing a trend equation for a predictive model based on geodetic data is presented, including: 1) determining the trend equation by a search method of nonlinear programming using a VBA-based search program; 2) assessment of the accuracy of determining the coefficients of the trend equations by using the search method of nonlinear programming; 3) assessment of the adequacy of trend models obtained by the search method. Based on the results of the analysis and calculations, an adequate trend model in the form of a logarithmic equation was established. The correctness of the conclusions was proved by the calculations carried out in Microsoft Excel and Statistica, which coincided with the results obtained. The predicted values of the deformation benchmarks were determined. 10.34910/MCE.114.4 528.3 geodetic measurements forecasting trend equation time series the adequacy of the model search method of nonlinear programming SDGs https://engstroy.spbstu.ru/article/2022.114.4/

 AHP-TOPSIS hybrid decision support system for dam site selection Inadequate selection of an area for the location of dams brings about social and economic disadvantages due to the non-fulfillment of its objective, as well as causes significant damage to the ecosystem of the river basin. This type of selection depends on a set of different criteria and variables, so it is necessary to develop a tool to support decision-making that allows reducing the collateral damage that a project of this type entails and increasing the project effectiveness. This paper proposes the development of a hybrid method of multicriterial analysis using the hierarchical analysis technique (AHP) and the technique for the order of preferences by similarity to the ideal solution (TOPSIS) with a specific focus on the selection of sites for dams. Modifications to traditional methods were established by eliminating the decision-maker as an evaluator of alternatives. The proposed method is based on the hierarchical ordering of alternatives taking into account the subjective judgments of decision-makers when considering the uncertainties of the selection process. The ordering of the alternatives is preceded by the analysis of a series of hydrological, geological, topographic and land use parameters extracted from a digital elevation model. According to the results obtained, it was possible to order hierarchically (better-worse) each of the river basins evaluated according to the established parameters. 10.34910/MCE.114.5 528.01:004.428:519.816 river basins selection of areas dams multicriterial analysis decision making AHP TOPSIS https://engstroy.spbstu.ru/article/2022.114.5/

 Forced vibrations of a box element of a multi-story building under dynamic impact The article is devoted to the dynamic calculations of the elements of the box-shaped structure of buildings for seismic resistance, taking into account the spatial work of the elements of the box under the action of dynamic influences set by the movement of their lower part according to the sinusoidal law. The equations of motion are given for each of the plate and beam elements of the box-shaped structure of the building on the basis of the Kirchhoff-Love theory. Expressions are given for the forces, moments and stresses of the plate elements that equalize the movement of the box elements, and the boundary conditions, as well as the conditions for full contact in terms of displacements and force factors in the contact zones of plate and beam elements. The general solution of the problem is constructed by the method of decomposition of the movement of the elements of the box according to their own forms using the method of finite differences. The calculation results were obtained in the form of diagrams over the height of the box of bending moments, plate elements working in bending, as well as shear stresses of plate elements. 10.34910/MCE.114.6 624.042 buildings box-like structure dynamic calculation displacement stress deformation equation of motion boundary conditions contact conditions https://engstroy.spbstu.ru/article/2022.114.6/

 Bond testing of salty-sand concrete reinforced with different rebars In this work, reinforced concrete (RC) test specimens, cast with different rebars (CA-50 Steel, Basalt Fiber Reinforced Polymer – BFRP and Glass Fiber Reinforced Polymer – GFRP) and different concrete mixtures (salty-sand and unsalty sand), were submitted to the pull-out tests in order to follow the bonding behavior between the concrete and the rebar. The use of salty-sand in concrete mixtures for building construction has grown, especially in places where regular sand is scarce. However, the salinity attacks the steel rebar in RC structures, resulting in corrosion problems, which can be strongly reduced by using composite material rebars which shows, similar or superior, mechanical strength, when compared to steel rebars. Conformance testing, including X-ray powder diffraction (XPD), scanning electronic microscopy (SEM) and tensile tests, were performed on the rebars, with the aim to check the conformity of the physical, chemical and mechanical properties. Standard cylindrical test specimens (diameter of 100 mm and a height of 200 mm) and RC test specimens were prepared for compression and pull-out tests performed at 63, 217 and 315 days, after casting. The results showed a bonding loss for the RC test samples molded with CA-50 steel rebar and salty-sand concrete. On the other hand, bonding loss was not detected for test samples molded with BFRP and GFRP rebars. In conclusion, the BFRP and GFRP rebars showed to be the proper ones to be used for salty-sand concrete mixtures, however, even having higher traction resistance, their use in the RC structures will demand higher anchor lengths. 10.34910/MCE.114.7 624.01 concrete structures chloride-induced corrosion bond stress FRP pull-out resistance https://engstroy.spbstu.ru/article/2022.114.7/

 Influence of electromagnetic field on characteristics of crushed materials This paper describes the findings of a study into the impact of the magnitude of induction and the frequency of rotation of an electromagnetic field on the properties of materials (Portland cement, gypsum plaster, limestone), which are treated in the vortex layer machines. The effects were assessed based on the following criteria: 1) the location of the maximum values of the specific surfaces in the factor space as determined by the Tovarov method based on the BET method and the temperature of the model powders following treatment in a vortex layer machine; 2) the symbasis of the change in the values of the specific surface as determined by the BET method and the temperature of the powders following activation. Theoretical and experimental studies have been used as a basis for putting forward the concept of treatment in vortex layer machines. The essence of the concept lies in boosting the defectiveness of particles (i.e. accumulation of defects) followed by defects emerging and particles dispersing. The maximum values of specific surfaces and of the temperature of powder upon activation can be obtained at an electromagnetic field rotation frequency of 66 Hz while the material being treated is mechanically activated at an electromagnetic field induction value of 0.21 T with Portland cement, 0.22 T with gypsum plaster and 0.23 T with limestone. A classification to define the susceptibility of the mineral component to treatment inside vortex layer machines has been proposed. 10.34910/MCE.114.8 691-408.66 cements energy efficiency specific surface area electromagnetic field https://engstroy.spbstu.ru/article/2022.114.8/

The generally accepted approach for trusses of bridge structures analysis is to replace joints with hinges. This technique simplifies finding the forces in structure elements, but reduces the reliability of the design model. In this study, the finite element method implemented in the Ansys Mechanical software package is used. The process of determining the stiffness of the high-strength bolts joint connection is described in detail. The paper proposes formulas to determine rotation angles of the truss elements joint sections according to the finite element model analysis results. For two joints of a standard design, superstructure stiffness was determined: kN2 = 107183.06 kN×m/rad, kN3 = 137605.56 kN×m/rad. Graphs of bending moment on the rotation angle dependence were also made. It was concluded that the beam model of the structure shows underestimated values of the joints stiffness, and the difference with the stiffness determined for the detailed finite element model can reach 5.635. 10.34910/MCE.114.9 624.31 connection stiffness semi-rigid connection steel truss railway bridge finite-element analysis Ansys Mechanical https://engstroy.spbstu.ru/article/2022.114.9/

 Functional indium oxide-based thin-film coatings with variable light transmission  One of the directions of energy-saving technologies development in the public works construction is associated with the engineering of glazing materials that allow regulating light and heat flux passing through them. Known solutions are associated with the use of multilayer materials with special optical thin-film electrochromic coatings. This work presents the results of the functional properties study of single-layer transparent conductive thin-film coatings based on tin-doped indium oxide (ITO films), formed on a glass substrate by magnetron sputtering. It is shown that, under conditions of cathodic treatment in a potentiodynamic mode at certain threshold potentials Ep in aqueous and aqueous-ethanol solutions, the introduction of hydrogen atoms into surface layers is observed, leading to a decrease in the transmittance Tx to ~10% and the transition of ITO films to a colored state. It was found that the introduction of hydrogen atoms is accompanied by the formation of hydrogen-indium bronzes with the general formula HxIn2O3, the composition of which depends on the pH of the solution. Indium bronzes formed in a neutral 3% NaCl solution are characterized by a low value of the x index, high conductivity and reversibility of the coloration-discoloration processes, i.e. have electrochromic properties. Indium bronzes formed in 1M aqueous and aqueous-ethanol KOH solutions have higher values of the x index, low conductivity and irreversibility of the coloring process. Increase bronzes conductivity due to the introduction of carbon nanoparticles into the outer layers of ITO films does not affect the reversibility of the coloration-discoloration processes. The results obtained can serve as a basis for the creation of a wide range of modern improved glass and double-glazed windows with an adjustable value of light transmittance. 10.34910/MCE.114.10 691.624 electrochromic properties optically active glazing material transparent-reflective switchable ITO films smart glass coating thin-film coatings magnetron sputtering transmittance smart windows switchable glass glazing systems https://engstroy.spbstu.ru/article/2022.114.10/

 Assessment of crack resistance of ultra-high earth core rockfill dam by pore pressure An important problem at construction of high earth core rockfill dams (ECRD) is danger of hydraulic fracturing of their seepage control element. It is usually considered that the cause of hydraulic fracturing is presence of micro cracks in the core, which open due to deficit of compressive stresses at penetration of reservoir water into it. However, this theory ignores the presence of the force in the soil core which fractures it from the inside, i.e. the pore pressure force. The author proposes the criterion of core crack resistance based on consideration of pore pressure. With the aid of numerical modeling of stress-strain state, the impact of pore pressure on potential development of cracks in the core of a 330 m high ECRD was studied. The considered dam has an inclined sandy loam core. By the results of analysis, it was established that the value and development of pore pressure are greatly influenced by the degree of water saturation S0 of clayey soil at its placement into the dam body. At S0 = 0.9 pore pressure in the core exceeds 4 MPa, and the zone of high pore pressure covers the most part of the core. At that, stresses in the soil skeleton (effective stresses) are still compressive stresses, which formally evidences about the core integrity. However, at S0 = 0.9 the zone of shear strength loss is formed in the core. It may be expected that failure of the core integrity during shear will result in hydraulic fracturing. Thus, pore pressure induces hydraulic fracturing. To prevent the core hydraulic fracturing, it is necessary to reduce pore pressure. Therefore, the clayey soil should be placed with moisture content by 15 % less than the optimal value. 10.34910/MCE.114.11 626/627 embankment dams pore pressure hydraulic fracturing cracks numerical analysis finite element method deformation earth core rockfill dam (ECRD) https://engstroy.spbstu.ru/article/2022.114.11/

 The influence of the sky radiative temperature on the building energy performance Most of the current sky models correlate with local climatic conditions and specific sites, while not covering different humidity-climatic conditions. In this work, sky emissivity and sky temperature models were reviewed, taking into account the common classification that includes simplified and detailed correlations. The clear-sky and cloudy-sky temperature models were also investigated in detail, employing them for different humidity-climatic conditions (wet, normal and dry) and evaluating their influence on building energy needs. Under clear-sky conditions in winter, the maximum difference between the ambient air temperature and sky temperature is 19 K regardless of humidity-climatic conditions. Under cloudy-sky conditions, it is possible to notice dissimilarities, ranging from 5 K (wet and normal conditions) to 10 K (dry conditions). In summer, under clear-sky conditions, the maximum values are ranging from 12 K (normal conditions) to 13 K (wet and dry conditions). Under cloudy-sky conditions, the maximum values are ranging from 5 K (normal conditions) to 10 K (dry conditions). Thus, the obtained results can be applied for the investigation of the radiative heat flux between a building surface and the sky, as a simplified model. Moreover, these results can be used when the sky temperature is not available from climatic data. The obtained results specified the simplified models according to ISO 13790. Finally, taking into account the influence of different correlations in building energy simulations, it was found that heating and cooling energy demands (using the example of a translucent roof) can be affected by significant percentage differences (the rounded values), ranging from +3 % to +11 % (no heat gain) for wet climatic conditions, from –61 % to +22 % for normal climatic conditions, and, finally, from −45 % to +8 % for dry climatic conditions. The comparison among the models can be useful to address the choice of users in building energy simulations and engineering applications. Future developments will regard the longwave sky radiation measurement under field conditions in the representative cities of the world in order to propose correlations for different climatic area. 10.34910/MCE.114.12 699.86 building building energy performance sky radiative temperature sky emissivity clear sky model cloudy sky model ambient air solar radiation environment https://engstroy.spbstu.ru/article/2022.114.12/

 High-performance fine-grained nanostructured concrete based on low strength aggregates This paper continues the authors' previous research on developing high-performance concretes based on low-strength aggregates. Unlike the previous work, where a low-strength crushed stone was used, the current research investigates a low-strength fine aggregate-based concrete. With modern construction chemistry in combination with pozzolan and high dispersed ground additives and nanomodification, it is possible to obtain high strength and operational characteristics concretes. The work carried out studies of three cement manufacturers for suitability in high-strength hydrotechnical concrete and phase analysis of the aggregates used in this study. Strength (7, 28, 180 days), density, waterproofness, freeze-thaw resistance of fine-grained concrete based on low-strength and high-strength aggregates were compared in the research. The final result is a concrete recipe with freeze-thaw resistance class F400, Waterproofing class W20 and compressive strength of 60.5 MPa at the age of 28 days (71.9 MPa at 180 days). 10.34910/MCE.114.13 691.3 high-performance concrete compressive strength fine-grained concrete basalt fiber silica fume https://engstroy.spbstu.ru/article/2022.114.13/

 Comprehensive assessment for optimal wind energy use in cottage construction The article considers the significance of an integrated assessment of the territory to ensure its sustainable development and use of its results when choosing a particular type of alternative energy source for a particular built-up area. RES (renewable energy sources) are types of energy that are continuously renewed in the Earth's biosphere (solar, wind, water, tidal energy, waves of water objects, including water bodies, rivers, seas, oceans, biogas, gas produced by waste products and consumption in landfills of such waste, gas generated from coal mining). The research presents a database of a geoinformation system for the selection and use of RES for housing construction, while multi-criteria evaluation is used in this case to determine the level of sustainable development of the territory of municipalities. The main factors in the selection and introduction of renewable energy sources in housing construction are the natural parameters, i.e. the wind region. Climate-forming factors of territory estimation are presented, as well as their dependence on climatic conditions. This system of territory assessment has been tested on the example of the Rostov Region in area of wind energy. Based on the maps built in ArcGIS ESRI, the territory of the Rostov Region is visually represented and its suitability is estimated for the introduction and development of wind energy source. The developed system is compared with the well-known works in the field of renewable energy sources; the use of GIS technologies reveals the advantages of the authors’ system. Detailed conclusions were made based on the results of the study: an integrated system for choosing the location of the RES are adapted for the conditions of the Rostov region. 10.34910/MCE.114.14 691.3 energy efficiency renewable energy sources optimization energy conservation sustainable development https://engstroy.spbstu.ru/article/2022.114.14/
